Abstract :The purpose of this study conducted in a raspberry garden in Karaagac central village of Usak province in 2017 and 2018 was to analyze the effects of phenological and pomological properties of different hormone applications on Heritage and Tulameen raspberry species in the ecology of Usak province . Our experiment was established as 3 replications with 10 plants in each replication. Hormones were applied as Giberallic acid insert ignore into journalissuearticles values(GA);, Melatonin insert ignore into journalissuearticles values(Mel); and GA+Mel with 2 different doses insert ignore into journalissuearticles values(5 ppm and 10 ppm); and 2.5 ppm melatonin and 2.5 ppm GA mixture for GA+Mel 5 ppm and 5 ppm melatonin and 5 ppm GA mixture for GA+Mel 10 ppm twice before blooming and fruit set.   When we analyze both species, we can see that blooming happens between 17 th  May and 18 th  June and the harvest is between 21 st  June and 12 th  September. In pomological measures, it was found that in both species fruit length was between 8.89 and 13.13 mm, fruit width was 9.76 and 13.68 mm and fruit weight   was between 0.64 and 1.29 g. While pH is between 3.62 and 4.80 and SSC is between 9.27% and 13.82%, TEA is between 21.62% and 30.56%. While Total Phenolic content insert ignore into journalissuearticles values(ppm/GAE); is between 3.91 and 5.33, Total Flavonoid content insert ignore into journalissuearticles values(ppm/QE); is between 0.75 and 1.42 and Antioxidant activity insert ignore into journalissuearticles values(IC50); is between 43.66 and 175.66, vitamin C insert ignore into journalissuearticles values(ppm); is between 1009 and 2308.50 values. According to the results we obtained in our study, Mel 10 ppm application in Tulameen cultivar in terms of pomological measurements and Heritage varieties in terms of chemical results and hormone applications in 5 ppm dose can be suggested in general terms.
